This may sound a bit harsh, but it's the cheaper route to permapetting. The perma-pet treatment also heals the cat if it is sick without you having to do anything else to heal it, so you can tuck it away in your inventory or your online cattery (if there is no food there) until it turns 121, and then permapet it at the lower cost without having to feed it until then. A lot of my permapets are actually sick collectibles that I've bought from people that were leaving SL or needed the money so I know this works. Of course, if you want it out, you can just leave breeding off until then and it eats 1/2 as much - or it's only L$300 more to do it before 121 days. The permapet lets you wake it whenever you want, with full energy, and I did it early with a toy-sized collectible so I could wear it on my shoulder and show it off whenever I wanted.
Regarding breeding - the pedigree links expire after 30 minutes so we can't see the ones you posted above, but it sounds like you already know that fur and eyes she's hiding. As you probably know, the fur on her is a costume, whic she can't pass and all her shown traits will be Genesis ones. I believe the traits are assigned when the box is first rezzed out in world, so, being an older collectible, she probably wouldn't have anything super new hiding. You could try to figure out other hiddens, but if you're not interested in what you've gotten so far, I'd probably stop spending the extra money on kibble.
Oh - the one thing you might check is whether those collectibles had special babies. They did -

It looks like the special baby is the "Deviled" bunny-eared one:

If you like the special baby, and want to go through the effort and expense to find a boy from the same collection (it can't be the special baby), the first time you put them together, they'll give you the special baby. After that though, they'll breed like regular starters.
